About:
SHTOOLS (Spherical Harmonic Tools) is a Fortran 95 library designed for working with spherical harmonics. It provides a comprehensive suite of functions for spherical harmonic transforms, spectral analysis, and gravity/magnetic field modeling. Its main value is offering a robust, open-source solution for geophysics and planetary science calculations.

Key Features:

Spherical harmonic transforms and inverses
Support for multiple spherical harmonic bases (geodesy, Fourier, Schmidt)
Tools for gravity and magnetic field modeling
Interface for Python, Matlab, and Julia
Fortran 95 library with C wrapper

Use Cases:

Modeling planetary gravity and magnetic fields
Topographic analysis of celestial bodies
Geodesy and geophysics research
Spectral analysis of global datasets

Alternatives:

pyshtools – Python wrapper for SHTOOLS; the Homebrew formula installs the core Fortran library.
libpsht – An older library optimized for CMB analysis, focusing on performance for specific spherical harmonic transforms.
